When my mom died, as traumatic an event as it was experiencing her sudden death, I had no regrets.
I must admit that I feel pretty happy, and fortunate, that I can say that.
Mom and I spoke almost every day, or, at a minimum, at least twice a week. Sundays was always a good time for us to catch up on each others comings and goings. We were very connected, except when I was a teenager of course!
